The Rat Patrol 1x26

Troy raids German HQ and kidnaps Dr. Schneidermann. At the same time Moffitt, Tully and Hitch are captured by Captain Dietrich. Dietrich reveals that Troy is carrying a vial of deadly radium. He urges Moffitt to divulge Troy's destination, bargaining the Patrols' unconditional freedom for the return of Schneidermann. Moffitt, disbelieving the radium story, keeps quiet. However Troy is carrying the fatal vessel. The three Patrollers escape and trail Troy back to the rendezvous, with Dietrich trailing them.
